Plug for sinks



March 1 0, 1931- HQ. A. TROTMAN 1" PLUG FOR SINKS Filed D513 20, 1929 Patented Mar. 10, 1931 r enrich Mrs HERBERT A. ,TROTMAN, or non'rn sen nrneo, oanrronnie PLUG ron sinks Application fi led December 20, 1929. .Serial No. 415,494.

This invention relates to improvements in devices for arresting the flow of water in sinks through the drains leading therefrom, and has as its general object to provide a device which may be employed by merely disposing the same over the perforated drain plate in the sink, where it will be held in place by the water flowing into the sink, so that the sink, in connection with which thedevice is employed, may be used for washing'dishes, pans, and clothing, this being more convenient than the use of a dish'or other type of p an, inasmuch as the ordinary sink is supplied with water from both hot and cold faucets and'therefore water at any desired temperature may be obtained.

Another object of the invention is to provide a device for the purpose stated which will be extremely simple in construction and 0 which will be so constructed as to preclude any displacementithereof in the event any of the articles, to be washed, come in contact therewith, the invention contemplating a device of this class which will primarily be held against displacement, in a very firm manner, by the weight of the volume of water in the sink, together with an auxiliary retaining means which will coact with the perforated drain plate of the sink to likewise resist any displacement of the device.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated 5 in the accompanying drawing, and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or rated drain plate thereof.

Figure 2 is a top plan view of the device removed from the sink. v

I Figure 3 is a bottom plan view of'the device removed.

The device embodying the invention comprises. an annular stopper disk 1 which is of soft rubber, and in the central opening 2 of this disk there is fitted a cap member, which is indicated in general by the numeral 3, and which may be stamped from sheet metal and comprises an annular wall a, an annular outstanding rim 5, and a bottom 6.

The wall 1- of the cap member is of a dia ".eter' to fit snugly into and substantial filling the opening 2 in the stopper disk 1, with the under side of the bottomfi of the cap member occupying the same plane as the under side of the said stopper disk, and with the rim 5 resting upon the upper side of said disk. The stopper disk 1 is of a diameter equal to or slightly greater than that of the drain closure or p ate which is indicated by the numeral 7, and which is formed with the usual perforations indicated by the numeral 8, and inasmuch the bottom of the cap member is in the same plane as the underside of the disk 1, the wei ht of the water introduced into the sink from the faucets, will securely hold the device in place when arranged in the manner shown in Figure 1.

In order that the device may be conveniently handled and in order to provide an auxiliary means for holding the device against displacement when arranged upon the drain plate 7, a bail 9, made of wire, is provided and this bail includes a. linger grip portion 10 which is straight and of a length less than the diameter of the wall 4 of the cap member, the wire being bent back upon itself as indicated by the numeral 11 so as to provide inturned portions 12 which rest upon the upper side of the bottom 6 of the cap member. These portions 12 terminate in downwardly extending right angular portions 11 which have their extremities turned in opposite directions as indicated by the numeral 1.3, so that, when the device is arranged in the manner shown in Figure 1, the portions 11 may be engaged through two diametrically oppositely located ones of the openings 8 in the drain plate 7 and, by a slight rotation of the device, the right angu- 4 lar terminal portions 12 may be caused to engage beneath the said plate 7 thus positively preventing upward displacement of the device until: it is intentionally rotated the 7 required distance to permit of passage of the members 11 and their extremities 13 through I nea th the drain plate.

. What I claim is i 1. A device of the class described comprising an annular disk of rubber, a head to which the disk is fitted, the headhavingga portion extending downwardly into the opening in its bottom with the under side of the disk and a fingerpiece coniiectedwith said head,"

I the head being open at itsupper side and proyided in its bottom :with diametrically op "positelylocated openings, and the said finger I piece having depe'nding'end portions engagmg through sa1d open1ngs,'and having right angularly turned terminals extending in opposite directions withrespect to the circumference of the disk, whereby, when the device 1s disposed upon a perforated dram plate in the said closure plate, thelower terminals of the saiddoWnwardly extending portions being presented in relatively opposite directionswhereby to engage beneath the closure pllate upon slight rotation of the plug, as a w ole.
